		<h1>Model-View-Controller</h1>

		<p>CodeIgniter is based on the Model-View-Controller development
			pattern. MVC is a software approach that separates application logic
			from presentation. In practice, it permits your web pages to contain
			minimal scripting since the presentation is separate from the PHP
			scripting.</p>

		<ul>
			<li>The <strong>Model</strong> represents your data structures.
				Typically your model classes will contain functions that help you
				retrieve, insert, and update information in your database.
			</li>
			<li>The <strong>View</strong> is the information that is being
				presented to a user. A View will normally be a web page, but in
				CodeIgniter, a view can also be a page fragment like a header or
				footer. It can also be an RSS page, or any other type of "page".
			</li>
			<li>The <strong>Controller</strong> serves as an <em>intermediary</em>
				between the Model, the View, and any other resources needed to
				process the HTTP request and generate a web page.
			</li>

		</ul>

		<p>CodeIgniter has a fairly loose approach to MVC since Models are
			not required. If you don't need the added separation, or find that
			maintaining models requires more complexity than you want, you can
			ignore them and build your application minimally using Controllers
			and Views. CodeIgniter also enables you to incorporate your own
			existing scripts, or even develop core libraries for the system,
			enabling you to work in a way that makes the most sense to you.</p>
